Attachment for a power stapler



July 3, 1962 J. BROWN ATTACHMENT FOR A POWER STAPLER Filed March 23, 1961 INVENTOR. BY JE s s BROWN .HlS ATTORNEYS United States Patent 3,041,620 ATTACHMENT FOR A POWER STAPLER Jess Brown, Chicago, 111., assiguor to Catherine E. Rhinevault, Chicago, Ill. Filed Mar. 23, 1961, Ser. No. 97,781 4 Claims. (Cl. 1-187) in a device of this character of a means for guiding a power driven staple into a predetermined configuration about a work piece.

Another principal object of this invention is in the provision in a device of this character of a means for closing the free ends of a staple so as to wrap the ends around an object in the manner of a hog ring as presently used in the furniture industry.

A still further object of this invention is in a provision in a device of this character of a means providing an open end work receiving opening relatively positioned with re spect to staple forming ends adapted to cooperate with suitable guides for stapling a work piece in a prede termined manner.

Yet, another object of this invention is in the provision in an attachment for a power stapler that is simple in use, etficient in operation and economical in manufacture.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings showing the preferred form of construction, and in which:

FIG. 1 is a perspective view of a power stapler and the improved attachment associated therewith;

FIG. 2 is a perspective view of the improved attachment;

FIG. 3 is a side elevational sectional detailed view of the attachment taken on lines 3-3 of FIG. 2;

FIG. 4 is a fragmentary plan view of the head of the improved attachment; and

FIG. 5 is a plan view of the staple in finished attaching form.

This invention relates to an attachment for a power stapler that will cause the driven staple to assume a closed condition. By a closed condition it is meant that the staple will have its free penetrating ends bent in the.

direction of each other and into an overlapping relation with respect to each other about a work piece or the like.

Referring to FIG. 1 I disclose a conventional power staple having a staple magazine 11. The attachment of this invention is adapted to be removably connected to the power stapler 10 so that staples contained in the magazine 11 will be successively positioned with respect to the attachment and the driving plunger of the power stapler 10.

The improved attachment comprises a substantially elongated body 12 terminating into an enlarged head 13. The enlarged head 13' is provided with a circular end 14 which has formed therein a work receiving slot 15. This Work receiving slot 15 is so formed as to extend in the direction of the longitudinal length of the body 12 as seen in FIGS. 2 and 4.

The enlarged head 13 has formed in one side face thereof a recess 16 which extends in the direction of the longitudinal length of the body 12 and slot 15. This recess 16 is of a width and length greater than that of slot 15 as seen in FIGS. 2, 3 and 4. The opposite walls 17 and 17 of the recess 16 provide therebetween a slide area which will receive and guide the staple driver and the driven staple. The slide area as provided by the recess 16 is adapted to be positioned relative to the staple maga- Zinc 11 as seen in FIG. 1 and thus will receive successive staples therefrom with the staple positioned in the slide area as defined by the recess 16 as seen in FIG. 4.

The recess 16 has one end thereof constructed in a manner to conform to the circular end 14 of the enlarged head 13. By this construction the recess provides spaced apart confronting forming ends 17 and 18. inwardly of the forming ends 17 and 18 and extending laterally from the base of the recess 16 are guide pins 19 and 20. These guide pins 19 and 20are so positioned with respect to the forming ends 17 and 18 that they provide therebe tween staple end bending grooves 21 and 22.

In operation the attachment body 12 is mounted to a power-stapler 10 in the manner shown in FIG. 1. A staple will be loaded on theattachment 12 in the position shown in FIG. 4. The work piece will be inserted into the slot 15. The plunger of the stapler 10 upon actuation will force the staple through the slide area provided' by the recess 16 into the direction of the slot 15.

'21 and 22 respectively. As the ends 23 and 24 of the staple engage the forming ends 17 and 18 they will be caused to be bent into the direction of each other. The work to be fastened will have been inserted into-the slot 15 and the staple ends 23 and 24 will be caused to be wrapped around the work piece as the staple is driven.

FIG. 5 discloses a staple A with the ends 23 and 24 thereof in their overlapping closed relation as accom plished through the employment of the attachment hereinbefore described.

By the construction of the attachment for a power. stapler as hereinbefore described it is evident that a work piece is readily applied to the power stapler. This open end work receiving slot 15 permits the use of a power stapler in industries such as. the furniture and upholstery industry wherein the work does not permit a staple forming apparatus to be placed in a spaced apart operative position with respect to the power stapler 10.

While this is illustrative of one of the many uses that this attachment may accomplish it is understood that the use and benefits of this invention are not to be limited in any manner.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of con- 1 struction set forth, but desire to avail myself of such varia tions and modifications as come within the scope of the appended claims.

Having thus described my invention, Whatl claim as new and desire to protect by Letters Patent is:
